Wound Closure Flashcards
What are 4 classifications of wound closure?
- Primary Closure
- Delayed Primary Closure
- Secondary Closure
- Contraction and Epithelialization (Second Intention Healing)
Immediate closure of a wound is known as what?
Primary Closure
What are 2 types of wounds for which primary closure can be used?
- Clean wounds
- Clean-contaminated wounds
A wound is considered clean-contaminated with what 3 factors?
- Intact host defense mechanisms
- Healthy wound
- Appropriate antimicrobial treatment
How long is a wound left open for delayed primary closure?
2-5 days
Delayed primary closure is performed prior to what?
Prior to visible formation of granulation tissue.
What does delayed primary closure permit?
Repeated lavage and debridement to convert wound to clean-contaminated status appropriate for closure.
Wound closure after granulation tissue covers the wound is known as what?
Secondary closure
What are 2 types of wounds for which secondary closure is indicated?
- Deep narrow wounds
- Wide wounds
How are deep narrow wounds closed?
Secondary closure by direct apposition over granulation tissue.
How are wide wounds closed?
Secondary closure by mobilizing skin edges and advancing over granulation tissue.
Contraction and epithelialization is also known as what?
Second intention healing
How should distal limbs wounds with damage less than or equal to 25% of the circumference heal?
25-33%?
33-50%?
Greater than 50%?
- Should heal well
- Most heal well
- Will probably heal but with a wider scar
- Consider reconstruction, extended healing time or inadequate healing
What are 3 causes of cessation of wound contraction?
- Wound has healed
- Tension in surrounding skin exceeds pull of myofibroblasts
- Collagen deposition in chronic wound interferes with pull of myofibroblasts
What are 2 possible complications of second intention healing?
- Circular wound
- Wound contracture
Where should closure lines be kept in relation to lines of tension?
Parallel
What are 3 reasons for making incision lines or wound closures on the trunk parallel to skin tension lines if possible?
- Gape less
- Heal faster
- More aesthetic
